Research on grinding temperature of particle-reinforced titanium matrix composites in creep-feed deep grinding

Particle-reinforced titanium matrix composites(PTMCs)have high specific strength,high hardness and high temperature durability,which shows great application potentials as an important structural material in aviation and aerospace industries.Creep-feed deep grinding experiments are carried out on particle-reinforced titanium matrix composite to study the grinding performance in terms of grinding temperature and surface.The heat distribution proportion in the workpiece is discussed using finite element method.The results show that grinding burn is likely to occur when the depth of cutting reaches 0.6 mm,and that grinding induced crack could be presented by a severe grinding burn.Moreover,the surface topography becomes worse with increasing depth of cutting.
